I actually regret doing all caps for PDB, and there seems to be mixed use
of all caps / rolling caps even with dwarf (some places say DWARF, others
say Dwarf).  I don't feel too strongly aside from the minor inconvenience
of having to change thousands of occurrences where I already used rolling
caps though :-/
